Canister Filter or??

[Treebeard]

I have a Eheim 2026 on my 46 gallon tank (dsb). Are you saying I should have no medias or filters in it? I also had an old Seaclone on the tank but finally turfed the pos because it was not producing a darn thing. I am in the market for a real hang on skimmer now.
